All photosynthetic eukaryotic cells contain chloroplasts that use the radiant energy of sunlight to convert carbon dioxide and water into carbohydrates. As a byproduct of photosynthesis, oxygen gas is also
released into the atmosphere through tiny openings in the leaves called stomata
.
What does photosynthesis produce?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create
oxygen and energy in the form of sugar
.
Does photosynthesis produce oxygen?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What is the source of oxygen released in photosynthesis carbon dioxide or water?
The oxygen released during photosynthesis is from
the water
. The plants will absorb water as well as carbon dioxide during photosynthesis. Later these water molecules are converted into oxygen and sugar. The oxygen is then released into the atmosphere whereas the sugar molecules are stored for energy.
Does photosynthesis produce ATP?
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons
return through ATP synthase
to make ATP.
Who has proved that oxygen evolved in photosynthesis comes from water?
Cornelius van Niel
showed that oxygen evolved in photosynthesis is from water and not carbon dioxide.
Where does the oxygen in CO2 go in photosynthesis?
The plant uses sunlight as energy to perform this chemical reaction. Photosynthesis separates carbon dioxide and water — known as CO2 and H2O, respectively — into their individual molecules and combines them into new products. Once the process is done, the plant releases Oxygen, or O2,
into the surrounding air
.
Do plants use ATP?
ATP can be
used to store energy for future reactions
or be withdrawn to pay for reactions when energy is required by the cell. … Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules.
How much ATP is used in photosynthesis?
Glucose combines with oxygen (oxidation), forming carbon dioxide, water and
38 molecules
of ATP.
What are the 3 stages of photosynthesis?
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP
+
to NADPH,
(3) generation of ATP, and (4) conversion of CO
2
into carbohydrates (carbon fixation)
.
Who proved that oxygen?
Joseph Priestley
(1733-1804) — Unitarian minister, teacher, author, and natural philosopher — was the Earl of Shelburne's librarian and tutor to his sons. In this room, then a working laboratory, Priestley pursued his investigations of gases. On 1 August 1774 he discovered oxygen.
What is the main point of photosynthesis?
The primary function of photosynthesis is
to convert solar energy into chemical energy and then store that chemical energy for future use
.
In which light photosynthesis is maximum?
Explanation. Maximum photosynthesis occurs in
red light
. When a plant is given monochromatic light (single light colour), the highest absorption of blue light is seen, but the highest photosynthesis rate is seen in red light. Light is absorbed by photosystem II that is membrane-bound.
What is the largest source of oxygen?
Scientists estimate that 50-80% of the oxygen production on Earth comes from
the ocean
. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize.
